FILING-MACHINE:

Specification of Letters Patent.

Patented Nov. 24, 1914.

Application filed June 12, 1913. Serial No. 773,224.

.To all whom it may concern:

Be it known that I, Josnrn ELPnnnms, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain .new and useful Improvements in Filing Machines; of which the following is a specification. y i

This invention relates to what I shall for convenience term a filing machine, one of the primary objects of the invention being to provide substantial and compact means for sustaining a driving shaft and an adjustable tool support which is mounted on said shaftas a center.

Another object is. the provision of guide means by which the movement of the tool through a straight path is insured.

Another object is the provision of means by which the work can be accurately and adjustably held with respect to the file or equivalent tool.

The machine :possesses other features of novelty and advantagewhich withthe foregoing will be stated at length in the following description wherein I set forth in detail that form of embodiment of the invention which I have selected for illustra tion in thedrawings accompanying and forming part of the present specification,

this disclosure being provided to enable Fig. 3 is atop plan view of a part of the bed. Fig. 4 is a front elevation of the tool, its carriers and support and certain cooperatingdevices hereinafter described. Fig.

5 is a transverse section of Fig. 6, the section being taken just (back of the screws 22. Fig. 6 1s a horizontal section on the line 6-6 of Fig. 4, and, Fig.7 1s a similar view,

ings, which it will be perceived are on different scales. 7

as shown best in Fig. 1.

said drawings: Figure 1 is.

characters refer to like parts.

The framework for supporting the different parts of the machine may be of anv suitable character that shown involving the base or bed 2 and the bearing or upright 3 rising therefrom, the latter being equipped with an overhanging arm 4.

As intimated the machine may be used in various connections, although it is of particular utility when employed for filing, for which reason the title hereinbeforc given has beenaclOpted. The file or equivalent toolis givena reciprocatory motion. and any suitable means may befurnished for this purpose, the shaft5 answering satisfactorily in this connection and being supported at its outer or rear end in a suitable openingin the overhanging arm 4 constitilting a convenient bearingmember and having a suitable driver such as the band wheel 6 fastened thereto. Said shaft is also shown provided with a balance wheel 7 all A tool such as the file 8 is sustained but not directlv, bv a support which may be of any suitable kind, the disk-like bracket or circular plate 9 being shown for this purpose, said disk or bracket 9. having upon its inner side the hollow hub or tubular pivot lO which fits and turns within the opening 11 at the outer end of the arm 4, this hub 10 presenting the outer support for the shaft 5. the enlarged 'cvlindrical portion 12 of which is rotativelv disposed within said hub or tubular hub 10. the bushing 13 (Fig. 1) being interposed between said enlargement 12and hub 10. The arm 4 is provided at its outer end with an annular flange magma which the d sk or bracket 9 fits flatwise. the flange and disk being aplproximatelv of equal diameter. a This provides asubstantial bearing, for the disk 9 transverse to its axis of oscillat on. said disk rocking whenbeing adjusted, on the shaft 5 as a pivot and also in the arm 4 when the stud 10 also acts as a ivot. The bracket 9, therefore. has a double bearing, and it in turn sustains the shaft 5, so that no independent bearing is necessary in this pa t cular connection.

The turning ofthe bracket 9 is to effect the angular adiustment of the file or equiva lent tool 8. there be ng two carriers inconjunction with said file. a main carrier as 15, and an auxiliary carrier or holder as 16 to which latterthe file 8 as will hereinafter appear, is directly connected. The main can H engage the same said screw being tapped.

rier 15 is reciprocatory, or slidable radially of the disk 9, receiving its motion in some suitable manner, as will hereinafter appear from the shaft 5 to thereby move the-file-S; up and down. The disk 9 is equipped with outward extensions or lugs 17 4 approximately diametrically opposite each other, which receive the reciprocatory main carrier 15. made substantially in the form of aslide square in cross section, longitudinal adjustments of the file being accomplished by; the endwise adjustment of the auxiliary carrier 16, the main carrier 15 having an opening its entire length to slidingly receive said auxiliary carrier or tool holder 16; The auxiliary carrier 16 is grooved as'at' 18 at its lower end to receive the tang of the file 8' which is rigidly held in said groove 18 by the clamping member 19 said carrier 16 being maintained in a longitudinally ad'- justed position by a set screw QO' adapted to through the main carrier 15. y

The circular flange 14 is shown having two arcuate slots 21' struck from the axis of rotation of the shaft 5', the screws 22 extending through said slots and being tapped into the support or disk the heads of said screws being adapted to engage against said fi'angeto hold-the support in an adjusted position.v By loosening the'screws the support canbe turned so as to vary the angle offpresentation of the file orother tool to the work. \Vhen the adjustment is secured the two screws are setand will maintain the adjustment. I

The shaft 5 is shown (-Figs'. 1 and 6) provided with a head23 (shown as a disk) at its outer end, disposed in the substan tially central 'counterbore 2st of the adjustable support 9; said head' having an adjust v able connectiomfor example through a stud.

hereinafter described, withthe-main ca r rier 15 so that the length of stroke of said carrier and therefore of the tool 8fconnected therewith canbe regulated. Said carrier 15 asillustrated,, has a transverseslot 25 (Figs. 1, 1 and 6) to receive the; antifriction' roller 26,the piv'ot'27' of which con sists ofa screw tappedsinto'thetee blocli 2-8 slidable in aradial tee'slot 2 9;which. extends outward from a point intersected by the axisof rotation of the shaft 5, by reason of" which said-block, on loosening'the screw 27,,

VVhen the axes of the screw- 1and shaft5 are coincident, the carrier 15" will not be h reciprocated but; by moving the screw 27' andtherefore anti-friction roller 26. away from he axisofr ta i go he haft h arrier 1 can r ip m ed th Shaft ernst sr atr li d ti efi nf he antir ric't on' roller n eit mj the; xi

The guide connected with the supportQ is denoted in a general way by 30, and it consists of an elongated bar preferably longitudinally adjustable as will hereinafter appear, the lower portion of the guide or base being curved inward and the active portion of said guide being provided with an anti-friction'roller or guiding member 31 supported" at the lower end of said bar and adapted to be engaged by the file as the samereciprocates during. work. As a convenient means for efiecting the longitudinal adjustment of the guide'or bar 30 the samemay be provided with longitudinal., superposed slots 32 through which extend the'shanks of binding screws 33 tapped into' the extensions 17. By loosening the binding screws the. guide may be longitudinally adjusted and when the. adjustment is secured thebinding'screws will be set-L, The second guide is designated by 8 1, and" it is shown as consisting of a' slide fitting acham- I I v tion roller 36 can be adjusted to a position to correspond with that of the cotiperatin'g anti-friction roller 31 whereby' during filing; or other work the'file' or equivalent tool 8 will: simultaneously engageboth anti friction rollers or active portions of the two guide' members to prevent flexing or bending of the file and thus insure accurate work.

As represented the row of threaded perforations 47 to inter ehangeably receive the pivot (shown as a screw) to thereby provide for the adjustment of said gage member or abutment 44 longitudinally of the slide or block 42. To maintain the angular adjustment of the gage member 44, the binding screw 48 may be provided, said binding screw being adapted tointerchangeably fit any one of said tapped holes or perforations 47, said screw extending through the arcuate slot 50 struck from the center of movement of the segment or plate 44.

What I claim is:

1. In a machine of the class described the combination of a support adjustable about an axis, a reciprocatory tool carrier on said support, a guide for the tool normally rigidly connected with said support, and a second guide for the tool mounted independently of the support and adjustable to conform to the position of the guide on the support on the adjustment of said support.

2. In a machine of the class described,

the combination of a support adjustable about an axis, a reciprocatory tool carrier on said support, a guide normally rigidly connectedwith said support and the active portion of which consists of an anti-friction roller, and an adjustable slide, sustained independently of said support and also constituting a guide, the active portion of the slide consisting of an anti-friction roller.

3. In a machine of the class described, the combination of a bearing, a support having a counterbore and having an inwardly extending hollow pivot, the hollow of which opens into said eounterbore, the pivot being supported by the bearing to provide for the angular adjustment of said support, a tool carrying slide on said support, a shaft extending through the hollow pivot and into said counter-bore, the shaft being also sustained by said bearing, and having a head in said eounterbore and means connected with said head for reciprocating said slide.

In testimony whereof I aflix my signature in presence of two witnesses.
